Britney Spears' lawyers from the firm of Trope and Trope were set to go before a judge on February 4 and explain why they wanted to discontinue representing their famous client in her custody battle with ex-husband Kevin Federline. But last week, the firm canceled those plans. So why did Brit's lawyers have a change of heart? According to an insider, a lawyer from the firm called Britney's parents, Lynne and Jamie, and gave them an ultimatum — they had to help intervene with their daughter or the firm was off the case.

"Britney never talked to them [her lawyers] and was not compliant," the insider says. "She didn't seem serious about fighting for her kids. She thought if she was paying them, then it was their job. One attorney told Lynne that Britney was a danger to herself and would never get her kids back if she didn't clean up her act. They were the reason Lynne finally came out here again."

Also last week, Britney's lawyers secured a new psychiatrist, who reportedly triggered the pop star's admittance on Wednesday night to UCLA Medical Center to undergo psychiatric evaluation.
